This is a standalone repro case for golang/go#40879

  • testdata contains logic to build 2 executables, bad and good.
    • They both have a CU DIE that uses DW_AT_ranges (to force this, I used a linker script to spread the code across 2 sections at different addresses)
    • bad has a .rela.debug_ranges section (it is linked with --emit-relocs)
  • main.go contains logic that prints the PC ranges of a binary.
  • test.sh will print the PC ranges using both the Go binary, and llvm-dwarfdump, to highlight the difference
  • make will compile all binaries and run test.sh on both good and bad, highlighting the difference.

Note: you need llvm installed (for llvm-dwarfdump). Alternatively you can change the test.sh script to use the regular dwarfdump.
